Seems there's a lot of interest in this for alts and deeds. Depending on other things I *may* be able to join but it's Snid's baby.
The hardest challenge is Fire and Frost, but with imbued LIs the full zerg strategy might work.
For Saruman you'll need to play Simon Says with the colours.

[EDIT] More interest needed to make this happen. Also, again, hard stop time at 10pm UK as I am currently very tired - unless someone else wants to lead *hopeful look*.
